Nikon D300 and Sony A700 Comparison
This is studio light comparison of Nikon D300 and Sony A700 DSLR camera. This indepth test was conducted by David Kilpatrick. The choice of scenery for these test shots are very good with lots of details and color. Nikon D300 noise level in this test without any NR under tungsten light is impressive and the level of details is fantastic with JPEG. The color in the sample look very good all the way up to ISO 6400, with ISO 6400 showing some saturation. The new Expeed images processor is excellent. If you turn the NR off, you will get more details in the Nikon D300 JPEGs compared to the Sony A700 from ISO 1600 and above. we’ve come to the point where DX camera noise is leveling out and things like AF will matter much more. I don’t think you will see any difference between A700 and D300 in ISO 100-400 resolution. They are both using the same sensor. At ISO 1600 it looks like Sony A700 used more aggressive noise reduction than Nikon D300. You can see more chroma noise in the D300 (than the A700) but also more detail. Nikon is adjusting for tungsten WB by cutting the red channel levels, instead of by boosting blue channel levels. This would explain the increased actual exposure, and the superior noise performance. We can do more test like this when we get the camera and compare raw files.
